Rock Ola 477 Max Problem
Posted: Thu Dec 08, 2011 7:48 pm
Hi I am a newbie and would be grateful if someone could give me some advice.
I had a couple of problems with my Rock Ola 477 where
1) the "LIGHT ON SPEAKER OVERLOAD" light was coming on as soon as a record was selected. I think I have resolved this by resoldering all the connections on both of the Driver PC Boards, although I need to test it out for a while.
2) When powered up the Record Magazine or Carousel jusr keeps turning and although you can hear the microswitch it seems to do nothing. I have metered out the microswitch on the opto board and check the wiring back to the logic board. As the carousel turns I can see the LED's on both the opto baord and the logic baord flashing.
If I select a record it plays it fine and then continues to rotate the magazine. I have run the "Logic Baord Test" and it plays the test selections but once again then goes back to rotating the magazine.
As I said I am a complete novice but would really appreciate some advice.
Thanks,
Mick
